| * NAME |
| * setfsuid02.c |
| * |
| * DESCRIPTION |
| * Testcase to test the basic functionality of the setfsuid(2) system |
| * call to fail on invalid uid. |
| * |
| * ALGORITHM |
| * Call setfsuid(2) and test the uid returned by setfsuid(2) when |
| * an invalid uid is used. |
| * If the returned value matches the invalid uid of the process, |
| * then the testcase fails. |
| * |
| * USAGE: <for command-line> |
| * setfsuid01 [-c n] [-f] [-i n] [-I x] [-P x] [-t] |
| * where, -c n : Run n copies concurrently. |
| * -f : Turn off functionality Testing. |
| * -i n : Execute test n times. |
| * -I x : Execute test for x seconds. |
| * -P x : Pause for x seconds between iterations. |
| * -t : Turn on syscall timing. |
| * |
| * HISTORY |
| * 07/2001 Ported by Wayne Boyer |
| * 04/2003 Adapted by Dustin Kirkland (k1rkland@us.ibm.com) |
